Hi I have a cleaner shrimp the red skunk one he has his own cave to himself but still goes in the clownfish’s territory and just sits there unbothered despite all the tail whips they give him. I got him Sunday but he’s a little shy and I do catch him outside caves sometimes I saw him digging in himself mostly his chest and picking out things not organs but I don’t know what that is I think he’s cleaning himself? Not too sure, also my LFS said I NEEDED live rock so the fish I plan to get (blue damsel) has somewhere to hide since they will fight over that one rock my clownfish are using my plants are fake since I’m a beginner but I got the live rock anyway but is it necessary? Could I have bought a fake rock? Or was she just trying to sell me something?
